Verdict

United Kingdom holds a 87–13 advantage over Belgium on the Relative Advantage Index, a decisive margin.

The margin is driven by military spending (86% of the combined total, $89.0bn) and economic size (GDP) (85% of the combined total, $3.7tn).

1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side. Those factors are excluded and the remaining weights renormalised, never substituted.
